4l80E PROBLEMS. CONVERTER, CLUTCHES, LOCKUP? WHO KNOWS WHAT IT IS?

[Chris092183]

Just recently my truck does this wierd slipping jolting motion when you apply more than about a 1/4 throttle. It almost feels like it is in gear then it slips out of gear then back in. It is definately more noticeable in 1st gear from a dead stop. I haven't had the 80e in that long, maybe 500 miles on it. The truck feels way slower now. I don't know what the hell it is but it is frusterating as . Could it be the stock verter, clutches valve body going out? Also the trans has been leaking alot. I think it's coming from the front of the trans...could it be the pump? Yes I do check and fill the fluid regularly so I don't think the prob is from low fluid levels.
Anybody know?

Tear it down and check it out. It may be a sticking pressure relief valve hanging open. Take it to a transmission shop and have them diagnose it.

Tough to tell from that post. Someone here or at a trans shop needs to experience the issue.

Could it be servo goin bad? Where doea the leak appearto be coming from? Front or rear of trans?

Ok, so i recently found out that you must use the longer fitting for the rear cooler lines in 97' and up 80e's. I did not initially install this fitting. I removed the 60e fitting and put the correct fitting in. My truck no longer does the jolting,slipping out of gear thing but my clutches and/or converter is/are definately burnt up. I was hoping the rear cooler line would fix all the probsbut due to the lack of fluid in the rear of the case I was reluctant that my internals would still be good. My truck still feels slow. Time for a rebuild.
